Are there two types of dwarf galaxies in the universe?

Posted 7 March 2013 by Marcel S. Pawlowski

Dwarf galaxies, that is galaxies less massive than a few billion solar masses, are expected to be formed through two processes. They might either be the luminous components of small dark matter halos, formed early in the universe when gas fell into the potential well of those halos. These dwarf galaxies are called primordial dwarf galaxies (PDGs) and are expected to be dominated by their dark matter content. The other formation mechanism is a process observed even in the present-day... Read more
